HEATING ATTACHMENT FOR KEROSENEI-BURNERS.

. Specification of Letters Patent.

Patented May 16, 1916.

Application filed september 18, 1915. Serial No. 5 1,404.

To all whom it may concern Be it known that I, ERWIN MAURER, a

citizen of the United States, residing atJamaica, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Heating Attachments for Kerosene- Burners, of which the following is a full, clear, and exact specification. a

This invention relates to vapor or gas burners, and has for its object to provide an improved heating attachment for cooking stove burners.

The invention contemplates the provision of a heating attachment which may be substituted for the detachable spreader of, a known type of cooking stove burner and is especially designed for use on the type of burner with which the Radius wickless kerosene stove is equipped, but may also be successfully employed on other forms of cooking stove burners in which fuel is mixed with air to form the proper vapor for burn- 111 Another object is to so construct the heating attachment that the gas or vapor which serves to heat this attachment may also be used at the same time for other purposes such as illumination.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute a part of this specification, and then more particularly defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views: Figure 1 is a sectional view, partly in elevation, of a heating attachment constructed in accordance with this invention and mounted in operative position on a burner of the type mentioned above, and Fig. 2 is an under plan view of the heating drum.

As the particular kind of burner does not constitute any part of the present invention, a general view of the preferred burner, namely that used on the Radius stove, is considered suflicient by way of illustration. In Fig. 1, this burner is indicated at 1, the gas or vapor delivery pipe being designated 2 and the usual vessel supporting frame shown at 7 in section. The burner is pro? vided with an upstanding flange 3 @9396?! trio with the gas supply pipe 2.

. A tube 4 has an enlarged portion or skirt 5 at its lower end surrounding the gas supply pipe 2 and rigidly secured to the flange 3 on the burner in any suitable manner for supporting the tube 4 in alinement with said gas supply pipe 2. The skirt 5 is perforated at 6, and the lower end of the tube 4:, where it joins onto the skirt 5, is spaced slightly above the upper end of the pipe 2. A conical heating drum 8 is mounted around the tube 4 with its upper end fitted closely around said tube.

At the lower end of the drum there is an inwardly extending base portion 9 to rest upon the vessel supporting frame 7. At the inner edge of the base 9 there is a depending flange 10 to fit within the frame 7 for holding the drum firmly in position. This flange 10 is spaced away from the upper end of the burner 1 so that air will circulate through the drum as indicated by the arrows, said air entering between the upper end of the burner and the flange 10 and escaping through perforations 12 in the upper end portion of the drum.

The base 9 of the drum may be extended outwardly to form a ledge 13 having a peripheral flange 14 for supporting flatirons,

as illustrated at 15 in Fig. 1. To protect the portion of the tube 4 which extends through the drum 8 from the intense heat in the drum, a casing of asbestos 16 is placed around this part of the tube.

The base 9 of the heating drum may have perforations 11 therein in any suitable number, providing additional inlets for air at the bottom of the drum. These perforations 11 are arranged over the open spaces in the vessel supporting frame 7, see Fig. 1. The tube 4 extends above the heating drum, so that the gas may be utilized for illumination or other purposes.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States is:

1. The combination with a kerosene burner having a gas supply pipe and a vessel supporting frame, of a tube connected to the burner for carrying the gas from the supply 'pipe, and a heating drum surrounding said tube and supported on the vessel supporting frame of the burner.

2. The combination with a kerosene burner having a gas supply pipe and a vessel supporting frame, of a tube mounted on the turmeric; conveying gas upwardly from the gas supply pipe,'and a heating drum of conical form mounted on the vessel suppprting frame to surround the tube and Having its tube, there being air inlet dpeni'ngsih thebottom of theclrum airexit openings-in the top portion thereof.

49. The combinatibn with a 'kercs'eneburnen haVihg a gas supply pipe and a vessel su porting frame, of" a tube mounted on the.

burner for conveying gasupvvafd'ly" elem the gas supply ipe, a heating drum to surround the tube mounted on the vessel supporting-frame anddiaving its upper end fittedclcsely around. saidtube, and a projecting ledge 'and'a peripheral flange on the outside eithedrum for the purpose specified;
